Definitions

  • the invention relates to a turbocharger according to the preamble of claim 1.
  • a turbocharger is known from WO 2004/048755A or the DE 20 2005 009 491 U1 known.
  • Another turbocharger is from the EP 1 398 463 A1 known.
  • a heat shield is provided around its shaft on the turbine side, which serves to protect the bearing housing from damage due to excessive temperatures due to the flowing through the turbine exhaust gases of the engine.
  • the known heat shield consists of a single-layer component, the thermal insulation properties, however, are in need of improvement.
  • turbocharger specified in the preamble of claim 1, which ensures a means of disc spring axial fixation of the cartridge of the variable turbine geometry in Turbinenradsupplementary and on the other hand allows improved thermal insulation in the direction of the bearing housing.
  • the disc spring is designed in combination with an insulator.
  • This insulator causes a lower component temperature of the plate spring and thus a higher contact pressure, on the other hand a lower heat input into the adjacent components (bearing housing).
  • the combination of heat protection layer, insulator and disc spring position can be either material or form-fitting, or it can be individually mounted in the turbocharger assembly, the items.
  • the insulator can be designed to shield the hot cartridge parts from the bearing housing.
  • the disc spring of the turbocharger according to the invention is formed from at least two, but optionally a plurality of material layers and includes both the function of the biasing force generation and the further improvement of the shielding function by increasing the thermal resistance. This makes it possible to ensure the function, especially at elevated exhaust gas temperatures.
  • u. U. advantageously be dispensed liquid cooling of the bearing housing.
  • Fig. 1 is a portion of a turbocharger 1 according to the invention shown, since this representation is sufficient for explaining the principles of the invention.
  • the turbocharger 1 all commonly provided construction elements, which, as I said in Fig. 1 however, are omitted for simplicity of illustration.
  • a turbine housing 2 of a turbine shown which is arranged adjacent to a bearing housing 3.
  • This bearing housing 3 is arranged between the turbine housing 2 and a compressor housing (not shown) of a likewise not shown compressor wheel.
  • the bearing housing 3 has the storage for a shaft which in Fig. 1 is symbolized by the reference symbol W since Fig. 1 only the upper portion of the turbocharger 1 according to the invention reproduces.
  • the shaft W carries the turbine and the compressor wheel and is mounted in the bearing housing 3 via a suitable bearing arrangement.
  • a disc spring 4 according to the invention is clamped, which is formed in multiple layers.
  • two material layers 5 and 6 are provided, which are described below with reference to Fig. 2 be explained in more detail.
  • Fig. 1 illustrates the arrangement of the disc spring 4 between the turbine housing 2 and the bearing housing 3, wherein the material layer 5 has a radially inner abutment portion 10 and a radially outer abutment portion 11 ', which is aligned parallel to a contact region 11 of the material layer 6.
  • An insulator 17 is clamped with a clamping region 18 between the material layers 5 and 6 or their contact areas 11 and 11 '.
  • the radially outer edge of the insulator 17 is angled at approximately 90 ° and thereby forms a support region 19, which supports the insulator 17 radially on the cartridge K.
  • the heat emitted by the cartridge K is effectively isolated from the bearing housing 3.
  • Fig. 2 the disc spring 4 according to the invention is shown in its entirety.
  • the two layers of material 5 and 6 in this embodiment are separate parts which are sandwiched together, including the clamping region 18 of the insulator 17.
  • Fig. 2 illustrates that the material layer 5 has a central recess 9 which is arranged coaxially to a central recess 8 of the material layer 6 and has a larger diameter. Between the layers of material 5 and 6, an air gap 7 is provided, which further improves the thermal insulation properties.
  • the material layer 5 has a main part 20 adjacent to the central recess 9, which is arranged at an obtuse angle to the abutment region 11 '.
  • the material layer 6 has a main part 21 adjacent to the central recess 8, which is integrally connected via an angled intermediate region 22 with the support area.
